CAM-based search engines and packet coprocessors include control logic
that supports direct reads of information that summarizes the done status
of multiple contexts being handled by the search engine device. This done
status information may be maintained in dedicated registers that are
configured to support high bandwidth utilization from a data port of the
search engine device. The control logic may also be configured to
generate interrupts or asynchronous signals that notify an issuing
command source of context completion.
